Drag Race Rear Lower Control Arms are for 1999-04 solid-axle equipped Mustangs with engine torque levels ranging up into the neighborhood of 1,000 ft-lb. That kind of Big Power requires rear lower control arms that are a step above the rest. Maximum Motorsports Drag Race series control arms provide the ride height adjustability essential to tuning for the optimum launch, along with the robustness required for hard launches at the strip with Big Power on slicks.Large spherical bearings at each end are tough enough for hard core drag racing, yet allow the angularity needed for proper suspension movement. This design aids traction at launch without degrading handling or street manners.
